A way to achieve this goal is to use Mockito and tell him to replace the @Autowired components in ...

All of the integration tests until now have used an in-memory embedded database that did not retain information from run to run. This changes when we fully integrate the REST server with a “real” database server ...

Introduction To JUnit Theories

Have you ever read a mathematical theory? It typically reads something like this: For all a, b > 0  the following is true: a+b > a and a+b > b Just typically the statements are more difficult to understand.
